Question on Student Rights

Hello all, I'm looking for advice. My friend won his case for a restraining order against his ex roommate here at SIUE but I'm worried because he said the campus police and admin haven't given him any guarantees of enforcing it or protecting him from this creep.

They're still allowing the guy to live on campus despite saying anti-lgbtq stuff and violating legal orders repeatedly. Is it really legal? Is there anything we can do to help him?

He said some things during the court proceedings that scared my friend pretty badly.
